Neil Ticktin writes in MacTech of his magazine's testing of two Windows virtualizers for Macintosh computers: Parallels and VmFusion. This class of software lets Apple computers run CAD software that would otherwise be locked to the Windows operating system. (For Linux, the equivalent is known as Wine.)
The testing didn't exactly involve CAD software; games, in fact, and timing the fps rate (frames per second). In all tests, Parallels was faster; in one case, it ran a game when VmWare could not.
The article is eight Web pages long, so here is the link to the conclusion page.
